I'm looking for a VGA solution to satisfy the requirements below:
1. support 5V supply
2. gain step size:0.5-1dB
3. gain range: -10dB to 15dB
Here is a reference design on how to do this for the LMH6521:
The same concepts will apply to this device, as it also features a self-biasing feature to 2.5V.
In regards to signal overshoot, I would confirm that you are not exceeding the abs…
Some of this information can be found in the datasheet for the LMH6521 datasheet which is from the same family of devices. Since the timing requirements seem to be missing from the datasheet of the LMH6522, I would recommend using the timings…
The output transformers have a 2:1 turns ratio presenting a 100-ohm on the secondary side and 50-ohm on the primary side. The two on-board 40.2-ohms + two 8-ohms LMH6521 output impedance along-with the 100-ohm on the secondary side of the transformer…
If i change the Clock Out 2 and 3 my sampling rate changes, but I can't reach the SPS of 77,8M. I read the User's guide, but they show a exemple with a 614,4 SPS. How in can reach the rate of 77,8 M?
I am sending the regs I use.
Part Number: LMH6522 Other Parts Discussed in Thread: ADC34J45 , , LMH6521 , TIDA-00073 , ADS41B49 , TINA-TI Hello,
My design will include the ADC34J45 that will have JESD204B interface to ALTERA ARRIA 10 FPGA.
The four analog inputs will be amplified by the…
Is your signal path single ended or differential? What load resistance do you need to drive? How linear do you jneed the signal at the output? 10V is pretty large for linear operation.
Our LMH6521 will drive a fairly large output signal, but…
The LMH6521 is our best, dual IF amplifier. THe LMH6401 is our highest bandwidth IF/RF amplifier, it is a single.
Gain flatness is a good proxy for phase consistency. An amplifier like the LMH6401 with a 0.1dB bandwidth of 500 MHz, will have…
